Since their introduction to Wurm "Rifts" appear frequently on the Freedom isles. When they do they not only spawn "alien structures" (crystals, columns, trees...), but they also deform and disfigure the landscape considerably. They create mounds, hills and even "spikes" with 20+ slopes. This not only occurs somewhere out in the wild, in the middle of nowhere, but also in developed and populated areas, even close to deeds. What is worse: the distortion also destroys roads, highways and even off-deed buildings.
Please change the rift mechanics so that the disfigurement of the landscape is minimized, and keep them away from highways, roads and user-built structures. Also: let the alien structures decay more rapidly.
(At the current high spawn rate, it will only be a matter of time until our servers will turn into strange alien landscapes...)
